    Abstract: An air pump has an air tank (20) for temporarily storing air from a pump unit (12) before discharging the air. The air tank has a tank body having a top wall (40) on which the pump unit is placed, and a peripheral wall (42) extending downward from the top wall. The tank body has a downward facing opening. The air tank further has a metallic bottom wall member (46) engaged with the bottom surface of the peripheral wall so as to close the opening of the tank body. Bolts are passed through the metallic bottom wall member and into a metallic part of the pump unit and tightened to connect and secure the pump unit and the air tank to each other.

    Abstract: A cryopump pumps gas from a vacuum chamber in a vacuum apparatus performing vacuum processing. The cryopump comprises: a refrigerator; a cryopanel cooled by the refrigerator; and a controller configured to control an operating cycle of the refrigerator such that the cryopanel is controlled so as to have a target temperature. When an operating cycle of the refrigerator has reached a first determination reference, the controller monitors the operating cycle for a first determination period of time, and when the operating cycle has reached a second determination reference, which corresponds to a higher load than the first determination reference, the controller monitors a temperature of the cryopanel for a second determination period of time, which is shorter the first determination period of time.

    Abstract: PROBLEM TO BE SOLVED: To monitor an operating state adapted to vacuum treatment in a vacuum apparatus in which an cryopump is installed.
    SOLUTION: A cryopump exhausts gas form a vacuum chamber of a vacuum apparatus that performs vacuum treatment. The cryopump includes a refrigerating machine, a cryopanel cooled by the refrigerating machine, and a control unit that controls an operation frequency of the refrigerating machine to control the cryopanel to a target temperature. The control unit monitors an operation frequency of the refrigerating machine for a first determination time period if the operation frequency of the refrigerating machine reaches a first reference, and monitors a temperature of the cryopanel for a second determination time period shorter than the first determination time period if the operation frequency reaches a second reference corresponding to a higher load than the first reference.

    Abstract: PURPOSE:To prevent overheating damage of the compressor by a method wherein the compressor is operated periodically by a control mechanism in a capacity increased to a predetermined value to retrieve lubricating oil separated from refrigerant in a refrigerant pipeline, a heat exchanger or the like when the signal of low capacity operation is being generated. CONSTITUTION:When the temperature of a room cooling machine is lowered, a thermostat 7A for a signal generating mechanism, determining the operating capacity of the compressor 1, is opened and a solenoid valve 2 is put OFF, the compressor 1 is operated in a low capacity such as 75% capacity, for example, and when the temperature is lowered further, the thermostat 7B is also opened and the solenoid valve 3 is also put OFF, the compressor 1 is operated in 50% capacity, for example. When the temperature is lowered further, the thermostat 7C is opened to cut the conduction of a relay 9 generating the signal of low capacity operation, a normally closed contact 11 is opened to put the solenoid valve 4 OFF and the compressor 1 is operated in 25% capacity operation. At the same time, a program timer 10, which is a timer mechanism, is operated, the normally closed contact 101 is opened for a time T1 and 25% capacity operation may be maintained. Thus, the lubricating oil, separated from the refrigerant in the refrigerant pipeline or a heat exchanger, is retrieved and thereby enabling to prevent the overheating damage of the compressor.

    Abstract: PROBLEM TO BE SOLVED: To efficiently cool a coil end on a compression part side in a coil of an electric motor.SOLUTION: In the electric motor, a refrigerant passage 51 that communicates a first region Z1 and a second region Z2 with each other is formed between a stator core 26 and a motor housing 11. In a journal member 19, a guide wall 19e is formed to guide a refrigerant so that the refrigerant that has flowed out from an outlet of the refrigerant passage 51 to the second region Z2 flows along an outer peripheral surface 272a in an axial direction of a second coil end 272. The refrigerant guided by the guide wall 19e is suctioned into a compression chamber 22 via a first through-hole 191h from the second region Z2.
